The other day I over filled a ce2 clearomizer with a bit too much juice, I couldn't really be bothered to syringe it back out so thought I'd just try burning it out a bit... It popped and crackled like crazy. Got massive blobs of extremely hot juice all over my coffee table. I then (stupidly) decided I'd straight up vape it... Like vaping molten lava...
Anyway, popping in my experience is generally no biggie, just be sure it's not because your atty isn't flooded though, you may even up with a mouth full of liquid if if pops in the middle of a vape.
